I recently received two new HP DL385 servers for a VMware install. The servers came with an additional NIC we use for redundant virtual switch ports. With the previous VMware install at another site, the NIC’s we ordered worked out of the box, but something was different enough about these HP NC365T cards that VMware did not recognize them.
After some research I found that I had to find and install the right drivers. According to the VMware Compatibility Guide the “igb version 220.127.116.11″ driver would work with these card. It would be cool if VMware provided a link directly to the download, but instead I had to go to the driver download page and find the right driver. I searched the page for 18.104.22.168 and found the drivers for Intel 82576 and 82580 NOTE: It appears there is an even new driver 2.4.10.
